Histological and Immunological Evaluation of Gastrointestinal Stromal Tumors
Background: Gastrointestinal stromal tumors (GISTs) constitute the majority of gastrointestinal mesenchymal tumors. They usually express a proto-oncogen protein called CD117 detected by immunohistochemistry. This study investigated the differentiation of GISTs as well as the risk of aggressive behaviors in GISTs from surgically-treated patients in university affiliated hospitals. Methods: The c...
متن کاملPediatric gastrointestinal stromal tumors.
Gastrointestinal stromal tumors (GISTs) rarely occur in pediatric patients, but increased recognition of adult GIST has led to better awareness of the existence of this entity in the pediatric population. GIST occurring in pediatric patients has a unique biology and clinical behavior and warrants discussion as an independent entity. The generally accepted definition of pediatric GIST is a tumor...
متن کاملImaging gastrointestinal stromal tumors.
BACKGROUND Because of the recent reclassification of mesenchymal tumors, which was based on a better understanding of the genetics and immunophenotype of gastrointestinal stromal tumors (GISTs), only a limited number of studies have described the radiologic appearance of GISTs. METHODS This study reviews the imaging characteristics of GISTs, with an emphasis on differentiating benign and mali...
متن کاملGastrointestinal Stromal Tumors
Background: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. A relationship to the interstitial cells of Cajal (ICCs) has been proposed, and expression of CD117, the c-kit receptor present in ICCs, has been suggested as a marker for GISTs. Methods: The English literature has been reviewed with an emphasis on histogenetic features, esp...
متن کاملSyndromic gastrointestinal stromal tumors
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of gastrointestinal tract. They feature heterogeneous triggering mechanisms, implying relevant clinical differences. The vast majority of GISTs are sporadic tumors. Rarely, however, GIST-prone syndromes occur, mostly depending on heritable GIST predisposing molecular defects involving the entire organism. These co...
